This is an awesome instructable, thanks. It's motivating me to learn blender. But I'm having a little, strange problem. When I use 3DEM to stitch 2 map tiles together (of a region I'm very familiar with), the result is stretched, so that later, when I'm playing with the uv_grid.png file, the proportions don't match. I tried redoing the whole thing from the start, but, same thing. The result that I get out of 3DEM is stretched, resulting in a stretched x3d and blender file which doesn't match the proportions of what I get out of google earth (actually using "Google Satellite Maps Downloader"). The thing is, I've already run through this tutorial several times with a different region (tweaking this and that and trying different specific areas, etc) where I only needed 1 map tile...

The thing is, I've already run through this tutorial several times with a different region (tweaking this and that and trying different specific areas, etc) where I only needed 1 map tile (so no stitching tiles in 3DEM) and there was no problem at all. Any insight would be greatly appreciated!
